Don’t invest in crypto.

No, because a cow has to be impregnated and their baby is taken away (and either killed (male) or is also going to be a milk cow (female)) just for you having some pleasure.

Not trusting in science.

Edit: Since there are many comments, I would like to clarify my statement. I meant that you should rather trust scientists, that the earth is round / that there is a human-made climate change, etc. and not listen to some random internet guy, that claims these things are false although he has made no scientific tests or he has no scientific background. I know that there are paradigm shifts in science and sometimes old ideas are proven to be wrong. But those shifts happen through other scientific experiments/thoughts. As long as > 99 % of all scientists think that something is true, you should rather trust them then any conspiracy theorist…
